Roof for vehicles

The invention relates to a roof for vehicles, in particular motor vehicles, which is made of plastic and includes support-like stiffeners at the edges.

The purpose of the invention is to create a plastic roof for motor vehicles that is suitable for the material Owns execution.

Plastic roofs are preferred in automotive engineering. the various possible uses and the weight savings. The disadvantage, however, is that they are in the area of the edges for reasons of strength must be reinforced by material accumulation, which becomes visible during the manufacture of the roof and therefore leads to undesirable surface irregularities.

Plastic roofs were to overcome these drawbacks already vorgesehlagen (US Patent 3 29Ö 73 ^) * ^be i where the edges are stiffened by bonded reinforcements. Although this design eliminates the disadvantage of the undesirable accumulation of material at the edge zones, it requires a large amount of tools and also makes it difficult to manufacture the roof cheaply and efficiently.

The invention is based on the object of creating a roof for motor vehicles, the edge zones of which have a production-ready roof Training and which at the same time can be put to good use.

The object is achieved according to the invention in that the roof is V-shaped in the area of the girder-like stiffeners Incision is provided which runs essentially parallel to one of the roof edges. For this it is advantageous

when the V-shaped linear step in the girder-like stiffeners extends along the outer edge of the roof, whereby one leg of the V-shaped profile is essentially parallel and runs at a distance from an adjacent inner wall of the roof. It is advantageous if the V-shaped ainocut in the girder-like stiffeners of the roof is formed by a gutter, the legs of which are angular synotrically to a horizontally extending wall of the roof are aligned. In a further embodiment of the iirfindunr, the width is between the bottom of the gutter and the horizontally running wall half as large as the thickness of the roof between the legs the gutter and its adjacent inner wall. After a - / purulent Feature of the 3rfindung can in the gutter of the roof Fastening elements may be provided that are used for holding Attachment devices or the like are used.

The advantages of the invention are mainly to be seen in the fact that the chosen design of the hand zones of the roof allows it to be produced in a rational and desrrnant way without fear of an unjustifiable waste due to material delay rnui. In addition, the incisions serve as a drainage channel, so that additional components are not required.
